To alllrwhom it may. concern:

Be itlrnown tllfi-iZLyJOHN DoNNnLLY, a citizen of the UnitedStates, residing 'at Branford, in the county of New Haven and State of Connecticut, have invented a new and useful Hacksaw-Frame; and I do hereby declare the following to be a 'full, clear, and exact description of theinvention, such as will enable others skilled in the art to Whichitappertains to make and use the same. .7 I I This invention relates to an improved hacksaw frame, and one of the objectsv of. the'invention is to providea frame of this kind having means whereby different lengths ofblades may be held thereby.

A further object of the invention is the provision of means for holding blades of different lengths, and in planes parallel or at right angles with the plane of the frame.

A further. object of the invention is the, provision of improved securing means for one end of said blade I In practical fieldsthe details ofconstruction may necessitate alterations falling within the scope of whatis claimed. V

The invention comprises further. features andcombination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings 7 z Figure 1 is a view in sideelevation ofthe improved hack saw frame constructed in accordance with the invention.

Fig. 2 is a view inside elevation; showing arts of the connections for the blade to: rame-in section, and illustrating the blade held at right anglesto that shown in'Fig. 1.

Fig. 3 is a detail perspective view of the means for connecting one end of the blade to the frame. I V l Fig. a is a detail-perspective view showing the opposite sides of themeans shown in Fig. 5 is a detail perspective view of the means for detachably connecting the inner end of the saw blade tothe'frame;

Fig. 6 is a detail sectional view online 6 6ofFig.4. "7 V Referring'moreespecially to the drawings 1 designates'the: main bar of. the hack saw frame. This bar. at its forward end is provided with an integral lateral extending part 2, which extends at an obtuse angle to the body of the bar. The outer edge of this I angularly extending part is constructed at right. angles to the body ofthe bar, as shown JOHN :DQNNELLY, or nitanronn, connncrron'rg H ACKSAW-FRAME,

at 3, and isprovided with a grounddepres r? sion 4., the' purpose'of;whichwilliappear later. 'A cyli'ndricalmember .5 is provided, V V

and this member is providedwith longitudig nally'jeXtending elongated slots. 6, extending at right angles to each other, and'into either I one of whichthe end portion, of the angu-.

larly extending part2may extend, as sh 7 V;

in Figs. 1 and2 clearly. One end of this member 5 is provided with a reduced-ear 7 which is provided'with apertures 8 and. 9. These apertureS'Sand 9 'ofi'set fromjoneanother angularly with-respect with thelongi- 'tudinal center of/the member 5., 1 One face of the ear 7 is provided witha groove 62(- tending from-the apertures 9 almost to the aperture- 8; Afastening device 11 comprise T ing a single length of wire is-provided.

' This fastening device. is bent upon "itself to form the straight portion 12, which engages the groove 10, While the arms13 and 14 extend through theaperturesSand It f I is to be noted that the arml l after-passing through aperture 9 is bent angularly and forwardly toward the body of the member 5, and is adapted 'to pas's; throughthe aperture 15 of one end of the hack sawblade The other armrl3 (which passes through the aperture 8), is bent as shown, to overlie the end portion of the hack saw blade. In order to connectthe-hacjk'saw blade 16, it is dis-i posed at right angles to the ear 7, as shown" I in dotted'lines in Fig. 3, afterjwhichfthe arm 14 is passed through the aperture 15 of the blade, then the blade is moved to extend in. alinement with the.member"5,,until the v 7 arm 13 overlies the blade, as shown inFig.

3 of the drawings The end portion of the angularly extending part 2 of the bar l'of tending lug17 to engage the-member 5,"to limitthe end partiof the'portion2 into any a U shapedstrap 19 is riveted asshown at 20. This strap slidably receives the bar 1 ofsaid frame, there being a laterally 'extend- V 1 I ing lug 21 at one endof-thebar 1 to prevent I removal of said strap; Thebar-18 at its end opposite the end having the strap19 has Y asv said frame is provided with a laterallyexsecured to it by rivets 22, a metallic plate 23.." This plate'23 is bent or curved to forma sleeve, which receives the shank 2450fv the] handle 25. .Itis to be noted that the shank may rotate in the sleeve, and; therearmarginal edge of thesleeve is. provided with other, encl o;

ehservetl that flogiies otthis petent maybe obtained for 1 scallops oi recesses 26 and 27. The scallops 1 er recesses 26 are diametrically opposite each" other while the recess 27 is at, rightnngles to the recesses 26. The shank 2% of the handle is provided with laterallfexteiirling pins 28; The forward encl of the shank 2e 13 cut away longitnoinally to form the recess'iZQ, and the fiat face of the recess is and its-show enters the eperture 31 the e hecksawblade; It is to he screw (which is thiieaclecl into the ten 7 Ward end; of 'the'member 5) inayengagethe depression Consequently rby setting up onthe set sei'en 82, and drawing the parts accordingly, the hack sew blade m ay be twhteneci, securely in place. It is to he noted that when the pin-28 engages the reeess 2-7, saiclhlafle mayheheltlon a'plene at' right angles to the SlClQftlCSS of the 1021i 1,

anclin this case the other slots6 at right tangles to those that previouslyieeeived the I v r end portion of the part2, may be engaged by thewencl portion of said part 2. By Vi -3; f V tue of the arm '13 fof the fastening means overlying the heck sewlhladeylsairl'blade is held inplace, nntilthe' parts are drawn se cure, by adjusting the thumb screw; 7 V

The invention having been set forthf 'wh t" jQIOVlClBCl with lug 30, which extends angulaily slightly reaxwai'clly towarcl the handle,
